Application filed December 2, 1920.

T 0 all'whom it may concern.

Be it known that I, VILLIAM F. RoEsoHER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Gas Ranges, of which the following is a specification.

My invention relates to improvements in gas ranges, the object of my invention being to provide novel means whereby a single set of burners may be employed both for surface cooking and for heating the oven of the range for baking purposes, said burners being so located with respect to the oven and the surface plates or supports as to give a maximum heating efl'ect and efficiency.

Figure 1, is a vertical section of a gas range made in accordance'with my invention, and

Fig. 2, is a view of the range partly in plan and partly horizontal section.

With reference to the drawings, 1 is the base and 2 the frame or casing of my gas range, said casing 2 enclosing an oven 3, admission to which is had by means of a door 4 pivotally secured to the said casing. The top of the range may be made in the usual manner with a gas manifold 5 eX tending across the front of the stove, from which extend suitable ducts or nipples 5 connecting the manifold with the burners 6. The top of the range preferably is equipped with solid plates 7 overlying the said burners 6. but when surface cooking alone is to be done, the ordinary open grid may be employed if this is desired.

\Vithin the casing 2 of the range are suitable partitions 8 which form between the casing walls and the walls of the oven flue passages for the hot gases of combustion from the burners, said flue extending inthe present instance downwardly along the back wall of the oven, forwardly underneath the oven, through suitable ports 9, 9, in the said partitions, one at each side of the bottom passage, and backwardly along the sides of the oven to a chamber 10 in the back of the casing, the gases entering said chamber through apertures 11, 11, one in each side of the rear partition and passing to the stack 12.

The front plate of the stove, through apertures 13 in which the burners 6 extend, may be equipped with separate draft holes,

Serial No. 427,732.

or, as shown in the drawings, the said apertures 13 through which the burners pass may be sli htly larger than the cross sectional area of the burners to provide an opening for the passage of air into the flue passages.

When the burners are lighted, the heated air passes downwardly at the back of the oven, forwardly underneath and then back along the sides thereof to the stack 12, a draft being thus formed which circulates the heated air entirely around the oven with the exception of the front wall, the heat of the surface burners being thus employed to heat the oven. The type of burner shown in Fig. 2 has been found particularly effective in my range.

The advantages of this construction are the reat saving in fuel which is accomplished thereby, and the efficient and safe action.

I claim:

1. The combination with a casing having flue openings, of an oven mounted therein with the walls thereof spaced apart from the walls of the casing, burners mounted in said casing directly above the top wall of the oven, and means for conducting the heated gases from the said burners to the flue openings past and in contact with the top, rear, bottom and side walls of the oven.

2. The combination of a casing, an oven mounted therein with the walls of the latter spaced apart from the walls of the casing, partitions constituting in effect continuations of the side walls of the oven and extending between the oven and the casing, said partitions having at the forward lower corners openings forming communication with the space between the said partitions and the spaces between the partitions and the side walls of the casing. and said casing having flue openings in said latter spaces, with burners established in the forward end of the casing directly above the top wall of the oven.

3. The combination with a casing, of an oven mounted within the casing with its walls spaced apart from the walls of the casing and with the door in the front wall of the casing, burners mounted at the front of the space between the top wall of the oven and the top wall of the casing ditures at the forward lower corners permitting the passage of the hot gases to the spaces between the sides of the oven and the 10 sides of the casing, and said casing having at the rear flue openings for the passage of the heated gases from the latter spaces.

WILLIAM F. ROESCHER.
